[0045] Figure 1 This is a block diagram of an electronic device 101 in a network environment 100 according to an embodiment.

[0046] Reference Figure 1In network environment 100, electronic device 101 can communicate with electronic device 102 via a first network 198 (e.g., a short-range wireless communication network), or with electronic device 104 or server 108 via a second network 199 (e.g., a long-range wireless communication network). According to an embodiment, electronic device 101 can communicate with electronic device 104 via server 108. According to an embodiment, electronic device 101 may include a processor 120, memory 130, input module 150, sound output module 155, display module 160, audio module 170, sensor module 176, interface 177, connection terminal 178, haptic module 179, camera module 180, power management module 188, battery 189, communication module 190, user identification module (SIM) 196, and / or antenna module 197. In some embodiments, at least one of the above components (e.g., connection terminal 178) may be omitted from electronic device 101, or one or more other components may be added to electronic device 101. In some embodiments, some of the components described above (e.g., sensor module 176, camera module 180, or antenna module 197) may be implemented as a single integrated component (e.g., display module 160).

[0047] Processor 120 may run software (e.g., program 140) to control at least one other component (e.g., hardware or software component) of electronic device 101 connected to processor 120, and may perform various data processing or calculations. According to one embodiment, as at least part of the data processing or calculation, processor 120 may store commands or data received from another component (e.g., sensor module 176 or communication module 190) in volatile memory 132, process the commands or data stored in volatile memory 132, and store the result data in non-volatile memory 134. According to an embodiment, processor 120 may include a main processor 121 (e.g., central processing unit (CPU) or application processor (AP)) or an auxiliary processor 123 (e.g., graphics processing unit (GPU), neural processing unit (NPU), image signal processor (ISP), sensor central processor, or communication processor (CP)) that is operationally independent of or combined with the main processor 121. For example, when electronic device 101 includes a main processor 121 and an auxiliary processor 123, the auxiliary processor 123 may be adapted to consume less power than the main processor 121, or to be dedicated to a specific function. The auxiliary processor 123 may be implemented separately from the main processor 121, or may be implemented as part of the main processor 121.

[0048] When the main processor 121 is inactive (e.g., in sleep mode), the auxiliary processor 123 (rather than the main processor 121) can control at least some of the functions or states associated with at least one component of the electronic device 1011 (e.g., display module 160, sensor module 176, or communication module 190), or when the main processor 121 is active (e.g., running an application), the auxiliary processor 123 can work with the main processor 121 to control at least some of the functions or states associated with at least one component of the electronic device 101 (e.g., display module 160, sensor module 176, or communication module 190). According to embodiments, the auxiliary processor 123 (e.g., an image signal processor or a communication processor) may be implemented as part of another component (e.g., camera module 180 or communication module 190) functionally associated with the auxiliary processor 123. According to embodiments, the auxiliary processor 123 (e.g., a neural processing unit) may include hardware architecture dedicated to artificial intelligence model processing. Artificial intelligence models can be generated through machine learning. For example, such learning can be performed via electronic device 101 where artificial intelligence is performed or via a separate server (e.g., server 108).

The artificial neural network may be a deep neural network (DNN), a convolutional neural network (CNN), a recurrent neural network (RNN), a restricted Boltzmann machine (RBM), a deep belief network (DBN), a bidirectional recurrent deep neural network (BRDNN), or a deep Q-network, or a combination of two or more thereof, but is not limited thereto. Additionally or optionally, the artificial intelligence model may include software structures in addition to hardware structures.

[0049] Memory 130 may store various data used by at least one component of electronic device 101 (e.g., processor 120 or sensor module 176). The various data may include, for example, software (e.g., program 140) and input or output data for commands associated with it.

[0052] The sound output module 155 can output sound signals to the outside of the electronic device 101. The sound output module 155 may include, for example, a speaker or a receiver. The speaker can be used for general purposes such as playing multimedia or playing records. The receiver can be used to receive incoming calls. According to an embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

[0053] Display module 160 can visually provide information to the outside of electronic device 101 (e.g., to a user). Display device 160 may include, for example, a display, a holographic device, or a projector, and control circuitry for controlling a respective one of the display, holographic device, and projector. According to an embodiment, display module 160 may include a touch sensor adapted to detect touch or a pressure sensor adapted to measure the intensity of the force caused by touch.

[0054] The audio module 170 can convert sound into electrical signals and vice versa. According to an embodiment, the audio module 170 can obtain sound via the input module 150, or output sound via the sound output module 155 or headphones of an external electronic device (e.g., electronic device 102) that is directly (e.g., wired) or wirelessly connected to the electronic device 101.

[0055] Sensor module 176 can detect the operating state of electronic device 101 (e.g., power or temperature) or the environmental state outside electronic device 101 (e.g., user state), and then generate an electrical signal or data value corresponding to the detected state. According to embodiments, sensor module 176 may include, for example, a gesture sensor, a gyroscope sensor, an atmospheric pressure sensor, a magnetic sensor, an accelerometer, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, and / or an illuminance sensor.

[0056] Interface 177 may support one or more specific protocols used to enable direct (e.g., wired) or wireless connection between electronic device 101 and external electronic device (e.g., electronic device 102). According to embodiments, interface 177 may include, for example, a High Definition Multimedia Interface (HDMI), a Universal Serial Bus (USB) interface, a Secure Digital Card (SD) interface, and / or an audio interface.

[0062] Communication module 190 can support the establishment of a direct (e.g., wired) or wireless communication channel between electronic device 101 and external electronic devices (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. Communication module 190 may include one or more communication processors capable of operating independently of processor 120 (e.g., application processor (AP)) and support direct (e.g., wired) or wireless communication. According to embodiments, communication module 190 may include wireless communication module 192 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 194 (e.g., local area network (LAN) communication module or power line communication (PLC) module). One of these communication modules can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, 5G network, next-generation communication network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components (e.g., multiple chips) that are separate from each other. The wireless communication module 192 can identify and verify the electronic device 101 in the communication network (such as the first network 198 or the second network 199) using user information (e.g., the International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

[0063] Wireless communication module 192 can support 5G networks following 4G networks and next-generation communication technologies (such as new radio (NR) access technologies). NR access technologies can support enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), or ultra-reliable low-latency communication (URLLC). Wireless communication module 192 can support high-frequency bands (e.g., millimeter-wave bands) to achieve, for example, high data transmission rates. Wireless communication module 192 can support various technologies used to ensure performance in high-frequency bands, such as, for example, beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, or massive antennas. Wireless communication module 192 can support various requirements specified in electronic device 101, external electronic devices (e.g., electronic device 104), or network systems (e.g., second network 199). According to an embodiment, the wireless communication module 192 may support peak data rates (e.g., 20 Gbps or greater) for implementing eMBB, lost coverage (e.g., 164 dB or less) for implementing mMTC, or U-plane latency (e.g., 0.5 ms or less for each of the downlink (DL) and uplink (UL), or 1 ms or less round trip) for implementing URLLC.

[0064] Antenna module 197 can transmit or receive signals or power to or from the exterior of electronic device 101 (e.g., external electronic device). According to an embodiment, antenna module 197 may include an antenna comprising a radiating element formed of a conductive material or conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, antenna module 197 may include multiple antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication scheme used in a communication network (such as a first network 198 or a second network 199) can be selected from the multiple antennas by, for example, communication module 190 (e.g., wireless communication module 192). Signals or power can then be transmitted or received between communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, additional components besides the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may be additionally incorporated into antenna module 197.

[0065] According to various embodiments, antenna module 197 may form a millimeter-wave antenna module. According to embodiments, the millimeter-wave antenna module may include a printed circuit board, a radio frequency integrated circuit (RFIC), and multiple antennas (e.g., an array antenna), wherein the RFIC is disposed on or adjacent to a first surface (e.g., a bottom surface) of the printed circuit board and is capable of supporting a specified high-frequency band (e.g., a millimeter-wave band), and the multiple antennas are disposed on or adjacent to a second surface (e.g., a top surface or a side surface) of the printed circuit board and are capable of transmitting or receiving signals in the specified high-frequency band.

[0066] At least some of the aforementioned components can be interconnected and communicate signals (e.g., commands or data) between them via an inter-peripheral communication scheme (e.g., bus, general purpose input / output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)).

[0067] According to an embodiment, commands or data can be sent or received between electronic device 101 and external electronic device 104 via server 108 connected to a second network 199. Each of electronic device 102 or electronic device 104 can be a device of the same type as electronic device 101, or a device of a different type. According to an embodiment, all or some operations that would be performed on electronic device 101 can be performed on one or more of external electronic devices 102, external electronic devices 104, or server 108. For example, if electronic device 101 is required to automatically perform a function or service, or is required to perform a function or service in response to a request from a user or another device, electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service, instead of running the function or service, or electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service in addition to running the function or service. Upon receiving the request, the one or more external electronic devices may perform at least a portion of the requested function or service, or perform additional functions or services related to the request, and transmit the result of the execution to electronic device 101. Electronic device 101 may provide the result as at least a partial response to the request, with or without further processing of the result. For this purpose, technologies such as cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing may be used. Electronic device 101 may use, for example, distributed computing or mobile edge computing to provide ultra-low latency services. In another embodiment, external electronic device 104 may include an Internet of Things (IoT) device. Server 108 may be an intelligent server using machine learning and / or neural networks. According to embodiments, external electronic device 104 or server 108 may be included in a second network 199.

The state in which the screen S is not extended is the state in which the second housing portion 22 does not move relative to the first housing portion 21 in a first direction (e.g., the +x axis direction), and can be referred to as the closed state of the electronic device 2. The state in which the screen S is extended is the state in which the second housing portion 22 does not move further in the first direction, i.e., it is moved to its maximum extent in the first direction, and can be referred to as the open state of the electronic device 2. In some embodiments, the open state may include a fully open state (see...). Figure 3a ) or intermediate state. An intermediate state can refer to a closed state (see...) Figure 2a The state between the first housing portion 21 and the fully open state. In some embodiments, when the second housing portion 22 moves at least partially relative to the first housing portion 21 in a first direction, this can be referred to as the "slide-out" of the second housing portion 22. In some embodiments, when the second housing portion 22 moves at least partially relative to the first housing portion 21 in a second direction opposite to the first direction (e.g., the -x-axis direction), this can be referred to as the "slide-in" of the second housing portion 22. Hereinafter, the first direction can be referred to as the "slide-out direction" and the second direction can be referred to as the "slide-in direction". In an electronic device 2 having an expandable screen S corresponding to the slide-out of the second housing portion 22, the flexible display 30 can be referred to by other terms such as "expandable display" or "slide-out display".

[0079] According to an embodiment, the screen S may include a first flat portion S1, a first curved portion S2, and / or a second curved portion S3. The first flat portion S1 may be interposed between the first curved portion S2 and the second curved portion S3. The first curved portion S2 and the second curved portion S3 may be curved from the first flat portion S1 toward the rear surface of the electronic device 2 (e.g., a surface positioned opposite to the screen S). The first curved portion S2 and the second curved portion S3 may be substantially symmetrical, for example, with the first flat portion S1 interposed therebetween. The first flat portion S1 may expand or contract depending on a change in the state of the electronic device 2 (e.g., switching between a closed state and an open state). Even when the state of the electronic device 2 changes, the second curved portion S3 may be provided in substantially the same shape. The portion of the second region ② of the flexible display 30 in which the second curved portion S3 forms may vary depending on a change in the state of the electronic device 2. The first curved portion S2 may be positioned relative to the second curved portion S3 in either the closed or open state of the electronic device 2 to improve the aesthetics of the screen S. According to some embodiments, the first flat portion S1 may be implemented as an extended form without the first curved portion S2.

The first rear cover 211 may be located on the opposite side of the screen S. When viewed from above the screen S (e.g., when viewed in the -z-axis direction), the first rear cover 211 may overlap with a portion of the screen S. The first side cover 212 may partially surround the space between the first rear cover 211 and the screen S, forming a side portion of the electronic device 2. The first side cover 212 may include, for example, a first cover portion 212a, a second cover portion 212b, and / or a third cover portion 212c. The first cover portion 212a may be positioned toward a first curved portion S2 of the screen S. The second cover portion 212b may extend from one end of the first cover portion 212a in a sliding direction (e.g., the +x-axis direction). The third cover portion 212c may extend from the other end of the first cover portion 212a in a sliding direction. According to an embodiment, the first cover portion 212a, the second cover portion 212b, and the third cover portion 212c may be integrally formed and comprise the same material (e.g., metal (e.g., aluminum, stainless steel (STS) or magnesium) or polymer).

[0081] According to an embodiment, the second housing portion 22 may include a second rear cover 221 and a second side cover 222. The second rear cover 221 may be located on the opposite side of the screen S. When viewed from above the screen S, the second rear cover 221 may overlap with a portion of the screen S. The second side cover 222 may partially surround the space between the second rear cover 221 and the screen S, forming a side portion of the electronic device 2. The second side cover 222 may include, for example, a first cover portion 222a positioned toward a second curved portion S3 of the screen S, a second cover portion 222b extending from one end of the first cover portion 222a in a sliding direction (e.g., the -x-axis direction), and / or a third cover portion 222c extending from the other end of the first cover portion 222a in a sliding direction. According to an embodiment, the first cover portion 222a, the second cover portion 222b, and the third cover portion 222c of the second side cover 222 may be integrally formed and comprise the same material (e.g., metal (e.g., aluminum, stainless steel (STS), or magnesium)) or polymer). The first cover portion 212a of the first side cover 212 and the first cover portion 222a of the second side cover 222 may extend parallel to each other in a third direction (e.g., the y-axis direction) orthogonal to the sliding direction (or sliding in direction). The second cover portion 212b of the first side cover 212 and the second cover portion 222b of the second side cover 222 may be positioned toward one edge of the screen S. The third cover portion 212c of the first side cover 212 and the third cover portion 222c of the second side cover 222 may be positioned toward the other edge of the screen S. The housing 20 may include a first boundary portion G1 between the first housing portion 21 and the second housing portion 22 corresponding to the first rear cover 211 and the second rear cover 221. The housing 20 may include a second boundary portion G2 between the first housing portion 21 and the second housing portion 22 corresponding to the second cover portion 212b of the first side cover 212 and the second cover portion 222b of the second side cover 222.

When viewed from above the screen S (e.g., when viewed in the -z-axis direction), the second boundary portion G2 and the third boundary portion G3 may be aligned in a third direction (e.g., the y-axis direction). When the electronic device 2 switches from an open state to a closed state, the first boundary portion G1, the second boundary portion G2, and the third boundary portion G3 may correspond to portions of the first housing portion 21 and the second housing portion 22 that are substantially adjacent to the outer shape of the electronic device 2.

[0082] According to an embodiment, the electronic device 2 may include a first support structure 41 (see...). Figure 3bThe first support structure 41 is connected to or at least partially integrally formed with the first housing portion 21. The first region ① of the flexible display 30 can be connected to the first support structure 41. The electronic device 2 may include a second support structure ( Figure 4 (Ref. 42) The second support structure corresponds to the second region ② of the flexible display 30 located in the second housing portion 22. During the sliding out of the second housing portion 22, due to the connection between the first support structure 41 to the first region ① and the second support structure ( ) corresponding to at least a portion of the second region ②, Figure 4 The spatial relationship between the reference numerals 42 and the second region ②, at least a portion of which can be reached through the first cover portion 222a and the second support structure ( Figure 4 The reference numeral 42) is pulled to the outside. During the sliding of the second housing portion 22, due to the connection between the first support structure 41 to the first region ① and the second support structure ( ) corresponding to at least a portion of the second region ②, Figure 4 The spatial relationship between the reference numerals 42 and the second region ②, at least a portion of which can be reached through the first cover portion 222a and the second support structure ( Figure 4 Reference numerals 42 and 43 are introduced into the housing 20. A surface of the first support structure 41, which is connected to the first region ① of the flexible display 30, may include, for example, a flat region and a curved region. The flat region of the first support structure 41 may contribute to the formation of the first flat portion S1 of the screen S. The curved region of the first support structure 41 may contribute to the formation of the first curved portion S2 of the screen S. The second curved portion S3 of the screen S may be formed corresponding to the second support structure (reference numerals 42 and 43). Figure 4 The curved portion (reference numeral 42) in the attached figure.

[0083] According to an embodiment, a first rear cover 211 may form a first rear surface B1 of the electronic device 2, and a second rear cover 221 may form a second rear surface B2 of the electronic device 2. The first rear surface B1 may include, for example, a second flat portion B11 parallel to a first flat portion S1 of the screen S and / or a third curved portion B12 corresponding to a first curved portion S2 of the screen S, curving from the second flat portion B11 toward the first curved portion S2. The second rear surface B2 may include, for example, a third flat portion B21 parallel to the first flat portion S1 of the screen S and / or a fourth curved portion B22 corresponding to a second curved portion S3 of the screen S, curving from the third flat portion B21 toward the second curved portion S3. The second flat portion B11 and the third flat portion B21 may be formed with substantially no height difference. In some embodiments, the second flat portion B11 may be implemented as an extended form without the third curved portion B12, or the third flat portion B21 may be implemented as an extended form without the fourth curved portion B22.

[0084] According to an embodiment, the first back cover 211 and / or the second back cover 221 may be opaque. The first back cover 211 and / or the second back cover 221 may be formed of, for example, coated or colored glass, ceramic, polymer, metal (e.g., aluminum, stainless steel (STS) or magnesium), or a combination of at least two of the above materials.

[0085] According to some embodiments, when the second region ② of the flexible display 30 is at least partially introduced into the internal space of the housing 20 (e.g., in the closed state of the electronic device 2), at least a portion of the second region ② can be seen from the outside through the second rear surface B2. In this case, at least a portion of the second rear cover 221 may be transparent or translucent. In some embodiments, when a member is inserted between the second rear cover 221 and at least a portion of the second region ② in the closed state of the electronic device 2, at least a portion of the member may include an opening or may be formed to be transparent or translucent.

[0086] According to embodiments, the sliding structure associated with the second housing portion 22 may include an elastic structure. For example, when the second housing portion 22 moves a preset distance by an external force, the second housing portion 22 can switch from a closed state to an open state or from an open state to a closed state without any external force due to the elastic structure included in the sliding structure (e.g., semi-automatic sliding motion). In some embodiments, when a signal is generated by an input device included in the electronic device 2, the electronic device 2 can switch from a closed state to an open state or from an open state to a closed state due to a drive device (such as a motor) connected to the second housing portion 22. For example, when a signal is generated by a hardware button or a software button provided via the screen S, the electronic device 2 can switch from a closed state to an open state or from an open state to a closed state. In some embodiments, when a signal is generated from various sensors such as a pressure sensor, the electronic device 2 can switch from a closed state to an open state or from an open state to a closed state.

[0087] According to an embodiment, the electronic device 2 may include a first camera module 271, a plurality of second camera modules 272, and / or a flash (or light-emitting module) 273. The first camera module 271 and / or the plurality of second camera modules 272 may include one or more lenses, image sensors, and / or image signal processors. The flash 273 may include, for example, a light-emitting diode or a xenon lamp.

[0088] First camera module 271 (e.g., Figure 1The camera module 180 can be aligned with an opening (e.g., a through-hole or notch) formed in the screen S to be located inside the electronic device 2. External light can pass through the opening and the portion of the transparent cover that overlaps with the opening to be introduced into the first camera module 271. The transparent cover can be used to protect the flexible display 30 from external influences and can be implemented as, for example, a flexible component, such as a plastic film (e.g., a polyimide film) or ultra-thin glass (UTG).

[0089] According to some embodiments, the first camera module 271 can be disposed at the bottom of at least a portion of the screen S and perform related functions (e.g., capturing images) without visually identifying (or exposing) its position. For example, the first camera module 271 can be located in the rear surface of the screen S, or below or beneath the screen S. The first camera module 271 can be aligned and positioned in a recess formed in the rear surface of the flexible display 30. When viewed from above the screen S (e.g., when viewed in the -z axis direction), the first camera module 271 can be configured to overlap with at least a portion of the screen S to obtain an image of an external object without being exposed to the outside. In this case, the portion of the flexible display 30 that at least partially overlaps with the first camera module 271 can include different pixel structures and / or wiring structures compared to other regions. For example, some regions of the flexible display 30 that at least partially overlap with the first camera module 271 can have different pixel densities compared to other regions. The pixel structures and / or wiring structures formed in the portion of the flexible display 30 that at least partially overlap with the first camera module 271 can reduce light loss between the outside and the first camera module 271. According to some embodiments, pixels may not be located in the portion of the flexible display 30 that at least partially overlaps with the first camera module 271.

[0090] Multiple second camera modules 272 (e.g., Figure 1 The camera module 180 and / or flash 273 may be located, for example, in the first housing portion 21 corresponding to the first rear surface B1 of the electronic device 2. The plurality of second camera modules 272 may have different characteristics (e.g., viewing angles) or functions, and include, for example, dual or triple cameras. In some embodiments, the plurality of second camera modules 272 may include lenses with different viewing angles, and the electronic device 2 may be controlled based on user selection to change the camera module executed therein. As another example, the plurality of second camera modules 272 may include at least one of a wide-angle camera, a telephoto camera, a color camera, a monochrome camera, or an infrared (IR) camera (e.g., a time-of-flight (TOF) camera, a structured light camera). The IR camera may, for example, serve as a sensor module (not shown) (e.g., Figure 1 At least a portion of the sensor module 176) is used to operate.

[0091] According to various embodiments (not shown), the electronic device 2 may include various sensor modules (e.g., Figure 1 The sensor module 176 can generate electrical signals or data values ​​corresponding to the internal operating state or external environmental state of the electronic device 2. The sensor module may include at least one of, for example, a proximity sensor, gesture sensor, gyroscope sensor, atmospheric sensor, magnetic sensor, accelerometer, grip sensor, color sensor, infrared (IR) sensor, biometric sensor (e.g., fingerprint sensor, heart rate monitor (HRM) sensor), temperature sensor, humidity sensor, or illuminance sensor. According to an embodiment, the sensor module may include an optical sensor and may be aligned with an opening (e.g., a through-hole or notch) formed in the flexible display 30 to be located inside the electronic device 2. In this case, external light can pass through the opening and the portion of the transparent cover overlapping the opening to be introduced into the optical sensor.

[0092] According to some embodiments, the sensor module can be disposed at the bottom of at least a portion of the screen S of the flexible display 30 and perform related functions without visually identifying (or exposing) its location. For example, the sensor module can be located in the rear surface of the screen S of the flexible display 30, or below or beneath the screen S of the flexible display 30. The sensor module can be aligned and positioned in a recess formed in the rear surface of the flexible display 30. When viewed from above the screen S (e.g., when viewed in the -z axis direction), the sensor module can be configured to overlap with at least a portion of the screen S and perform corresponding functions without being exposed to the outside. In this case, the portion of the flexible display 30 that at least partially overlaps with the sensor module can include a pixel structure and / or wiring structure different from the pixel structure and / or wiring structure of other regions. For example, some regions of the flexible display 30 that at least partially overlap with the sensor module can have different pixel densities compared to other regions. The pixel structure and / or wiring structure formed in the portion of the flexible display 30 that at least partially overlaps with the sensor module can reduce loss when various types of signals (e.g., light or ultrasound) associated with the sensor module pass between the outside and the sensor module. According to some embodiments, multiple pixels may not be located in the portion of the flexible display 30 that at least partially overlaps with the sensor module.

[0093] According to an embodiment, the electronic device 2 may include one or more key input devices 275 (e.g., Figure 1 The input module 150). In some embodiments (not shown), the key input device may include at least one sensor module.

[0094] According to various embodiments, the electronic device 2 may omit at least one component or may additionally include other components. For example, the electronic device 2 may include a microphone located inside the housing 20 and a corresponding microphone hole formed in the housing 20. According to some embodiments, the electronic device 2 may include multiple microphones capable of detecting the direction of sound.

For example, the electronic device 2 may include a receiver for calling located inside the housing 20 and a corresponding receiver hole formed in the housing 20. In some embodiments, the microphone hole and the speaker hole may be implemented as a single hole, or the speaker hole may be omitted, as in a piezoelectric speaker. For example, the electronic device 2 may include a connector (e.g., a USB connector) located inside the housing 20. Figure 1 The electronic device 2 has a connecting end 178 and a corresponding connector hole formed in the housing 20. The electronic device 2 can send power and / or data to, and / or receive power and / or data from, external electronic devices electrically connected to the connector through the connector hole. According to various embodiments, the electronic device 2 may include… Figure 1 The electronic device 101, or may include Figure 1 At least one component of the electronic device 101.

[0097] According to an embodiment, the first housing portion 21 may include a first rear cover 211, a first side cover 212, and / or a first support structure 41. The first support structure 41 may be coupled to the first side cover 212, or may be at least partially integrally formed with the first housing portion 21. The first support structure 41 is a load-bearing frame structure (e.g., a first bracket) and may contribute to the durability or rigidity of the electronic device 2. The first support structure 41 may include a plurality of support members, such as a first support member 411 and a second support member 412. The first support member 411 may be integrally formed with the first side cover 212. The second support member 412 may be coupled to the first support member 411 and / or the first side cover 212 using various methods such as bolting or joining. The first rear cover 211 may be disposed in the first support member 411. A first region ① of the flexible display 30 may be disposed in the second support member 412. For example, the first region ① of the flexible display 30 may be disposed in the second support member 412 using a thermally reactive adhesive, a photoreactive adhesive, a common adhesive, and / or double-sided tape. The first support structure 41 is not limited to the example shown, and can be implemented in various other forms.

[0098] According to an embodiment, the second housing portion 22 may include a second rear cover 221, a second side cover 222, and / or a second support structure 42. The second support structure 42 may be coupled to the second side cover 222, or may be at least partially integrally formed with the second side cover 222. The second support structure 42 is a load-bearing frame structure (e.g., a second bracket) and may contribute to the durability or rigidity of the electronic device 2. The second support structure 42 may include multiple support members, such as a third support member 421 and a fourth support member 422. The third support member 421 may be integrally formed with the second side cover 222. The second rear cover 221 may be disposed within the third support member 421. The fourth support member 422 may be coupled to the second side cover 222 using various methods such as bolting or engagement. The fourth support member 422 may include a bent portion 422a positioned corresponding to and facing the first cover portion 222a of the second side cover 222. In some embodiments, the fourth support member 422 may be referred to as a "bent member," a "bent support member," or a "bent support structure." One end of the fourth support member 422 may be connected to the second cover portion 222b or a separate support member disposed in the second cover portion 222b. The other end of the fourth support member 422 may be connected to the third cover portion 222c or a separate support member disposed in the third cover portion 222c. During the sliding out of the second housing portion 22, the fourth support member 422 may move away from the first support structure 41 connected to the first region ① of the flexible display 30, and at least a portion of the second region ② included in the flexible display 30 may be pulled to the outside through the bending space between the first cover portion 222a and the fourth support member 422. During the sliding in of the second housing portion 22, the fourth support member 422 may approach the first support structure 41 connected to the first region ①, and at least a portion of the second region ② may be introduced into the housing 20 through the bending space between the first cover portion 222a and the fourth support member 422.

[0099] In some embodiments, the electronic device 2 may include a sliding actuator connecting a first housing portion 21 and a second housing portion 22. The sliding actuator can facilitate the smooth sliding out or inward movement of the second housing portion 22 relative to the first housing portion 21. The sliding actuator can be drivably connected to the first housing portion 21 and the second housing portion 22 such that the second housing portion 22 moves substantially relative to the first housing portion 21 in a sliding out direction (e.g., the +x-axis direction) or a sliding in direction (e.g., the -x-axis direction). The sliding actuator can provide a driving force for the sliding operation of the second housing portion 22 relative to the first housing portion 21. For example, the sliding actuator may include an elastic structure that provides a driving force that enables the second housing portion 22 to slide out or in without the user providing external force. As another example, the sliding actuator may include a drive mechanism such as a motor and provide a driving force that enables the second housing portion 22 to slide out or in without the user providing external force.

[0100] According to an embodiment, the sliding actuator may include at least one hinge. The hinge may include, for example, a linkage assembly. The linkage assembly may include a linkage structure (e.g., a link and a joint connecting the link) connecting the second support member 412 and the fourth support member 422, and an elastic member (e.g., a torsion spring) located within the linkage structure. For example, during the sliding out of the second housing portion 22, the elastic member may apply a spring force to unfold the linkage structure. The sliding actuator may be implemented as a variety of other types of hinges. The sliding actuator is not limited to hinges and may be implemented in various other forms.

[0101] The printed circuit board 43 (e.g., a rigid PCB (RPCB), flexible PCB (FPCB), or rigid-flexible PCB (RFPCB)) and / or battery 44 may be disposed within the internal space 505 of the first housing portion 21 at or connected to the first support structure 41. When viewed from above the screen S (e.g., when viewed in the -z axis direction), the PCB 43 and battery 44 may not overlap each other. The PCB 43 may be electrically connected to the flexible display 30 via, for example, a flexible PCB (FPCB) (not shown). For example, a processor (e.g., ...) may be mounted in the PCB 43.

The rear surface of the flexible display 30 may refer to a surface positioned relative to the surface from which light is emitted from a display panel comprising a plurality of pixels. In an embodiment, the display support structure 50 may be disposed on the rear surface of the second region ② included in the flexible display 30. When the second housing portion 22 slides out or in, the display support structure 50 may move by friction with the curved portion 422a of the fourth support member 422. The display support structure 50 may support the second region ② such that the second region ② of the flexible display 30 remains smoothly connected to the first region ① of the flexible display 30. In the closed or open state of the electronic device 2, a portion of the display support structure 50 may support the second region ② between the curved portion 422a of the fourth support member 422 and the second region ②. In the open state of the electronic device 2, for example, a portion of the display support structure 50 may support the first flat portion S1 included in the screen S. The display support structure 50 may contribute, for example, to the fact that in the closed state of the electronic device 2 (see Figure 5 ) and open state (see Figure 6 During the switching between regions, the second region ② moves while maintaining a smooth connection to the first region ①.

[0103] The display support structure 50 may include a first surface 501 facing the second region ② of the flexible display 30 and a second surface 502 positioned opposite to the first surface 501. In embodiments, the display support structure 50 may include a multi-bar structure (or multi-bar assembly). The multi-bar structure may include a plurality of support bars, for example, extending in a third direction (e.g., the y-axis direction) orthogonal to a first sliding direction (e.g., the +x-axis direction), arranged in the second surface 502. Due to the relatively thin thickness of portions between the plurality of support bars, the multi-bar structure can be flexible. In some embodiments, the multi-bar structure may be implemented without portions connecting the plurality of support bars. In some embodiments, the multi-bar structure may be referred to by other terms, such as "flexible track".

[0104] According to an embodiment, the electronic device 2 may include a track portion for guiding the movement of the display support structure 50.

One side of the display support structure 50 may be located at or inserted into the first guide rail 611, and the other side of the display support structure 50 may be located at or inserted into the second guide rail 621. The first guide rail 611 and the second guide rail 621 may include grooves or recesses corresponding to the movement path of the display support structure 50. The display support structure 50 can be guided and moved by the first guide rail 611 and the second guide rail 621. The first guide rail 611 and the second guide rail 621 can be substantially symmetrical based on the center line C of the electronic device 2 extending in the sliding or sliding direction (e.g., the x-axis direction). The center line C of the electronic device 2 can be used as a reference line for symmetry about the screen S. In some embodiments, the second cover portion 222b of the third support structure 61 and the second side cover 222 can be integrally formed, and the third cover portion 222c of the fourth support structure 62 and the second side cover 222 can be integrally formed.

[0105] A sliding structure for sliding out or in the second housing portion 22 can be provided between the first housing portion 21 and the second housing portion 22. In an embodiment, the first support structure 41 may include a first sliding portion (not shown) located at or inserted into the first guide rail 611 of the third support structure 61. The first support structure 41 may include a second sliding portion (not shown) located at or inserted into the second guide rail 621 of the fourth support structure 62. When the electronic device 2 is in Figure 5 The closed state and Figure 6 When switching between the open and closed states, sliding may occur between the first sliding part and the first guide rail 611, and between the second sliding part and the second guide rail 621.

[0106] According to some embodiments, the electronic device 2 may further include a support sheet 70 disposed on or attached to the rear surface of the flexible display 30. In this case, the display support structure 50 may be disposed in the support sheet 70. The support sheet 70 can contribute to the durability of the flexible display 30. The support sheet 70 can reduce the impact of... Figure 5 The closed state and Figure 6The load or stress that may occur during the switching between open and closed states affects the flexible display 30. When the second housing portion 22 moves, the support piece 70 can prevent the flexible display 30 from being damaged by the forces transmitted from it.

[0107] Along Figure 4 The cross-sectional structure 401 taken by line D-D' may include, for example, a flexible display 30, a transparent cover 35, an optically transparent adhesive member 36, and / or a support sheet 70. The flexible display 30 may be attached to the transparent cover 35 using the optically transparent adhesive member 36 (e.g., optically transparent adhesive (OCA), optically transparent resin (OCR), or super-visual resin (SVR)). The transparent cover 35 (e.g., a window) may cover the flexible display 30 to protect it from external influences. The transparent cover 35 may be implemented in the form of a flexible film (e.g., a film layer). The transparent cover 35 may include, for example, a plastic film (e.g., a polyimide film) or thin glass (e.g., ultra-thin glass). In some embodiments, the transparent cover 35 may include multiple layers. For example, the transparent cover 35 may have a form in which various coatings are disposed on the plastic film or thin glass. For example, the transparent cover 35 may have a form in which at least one protective layer or coating of a polymeric material (e.g., polyester (PET), polyimide (PI), or thermoplastic polyurethane (TPU)) is disposed in the plastic film or thin glass.

[0108] The flexible display 30 may include, for example, a display panel 31, a base film 32, a lower panel 33, or an optical layer 34. The display panel 31 may be interposed between the optical layer 34 and the base film 32. The base film 32 may be interposed between the display panel 31 and the lower panel 33. The optical layer 34 may be interposed between an optically transparent adhesive member 36 and the display panel 31. Various polymer adhesive members (not shown) may be disposed between the display panel 31 and the base film 32, between the base film 32 and the lower panel 33, and / or between the display panel 31 and the optical layer 34. The display panel 31 may include, for example, a light-emitting layer 31a, a thin-film transistor (TFT) film 31b, and / or an encapsulation (e.g., a thin-film encapsulation (TFE)) 31c. The light-emitting layer 31a may include, for example, a plurality of pixels implemented as a light-emitting device such as an organic light-emitting diode (OLED) or a micro-LED. The light-emitting layer 31a may be disposed in the TFT film 31b by evaporation of an organic material. The TFT film 31b may be interposed between the light-emitting layer 31a and the base film 32. TFT film 31b can refer to a film structure in which at least one TFT is disposed on a flexible substrate (e.g., a PI film) through a series of processes such as deposition, patterning, and etching. At least one TFT can control the current to the light-emitting element of the light-emitting layer 31a to turn the pixel on or off or adjust the brightness of the pixel. At least one TFT can be implemented as, for example, an amorphous silicon (a-Si) TFT, a liquid crystal polymer (LCP) TFT, a low-temperature polycrystalline oxide (LTPO) TFT, or a low-temperature polycrystalline silicon (LTPS) TFT. Display panel 31 may include a storage capacitor that can hold the voltage signal to the pixel, maintain the voltage applied to the pixel within a frame, or reduce gate voltage variations of the TFT due to leakage during the light-emitting time. By controlling the routines of at least one TFT (e.g., initialization, data writing), the storage capacitor can maintain the voltage applied to the pixel at predetermined time intervals. In embodiments, display panel 31 can be implemented based on an OLED, and encapsulation 31c can cover the light-emitting layer 31a. Electrodes and light-emitting organic materials in an OLED may be highly sensitive to oxygen and / or moisture, thereby losing their light-emitting properties. Encapsulation 31c seals the light-emitting layer 31a, preventing oxygen and / or moisture from penetrating the OLED. The base film 32 may comprise a flexible film made of a polymer or plastic such as PI or PET. The base film 32 can be used to support and protect the display panel 31. In some embodiments, the base film 32 may be referred to as a "protective film," "back film," or "backsheet."

[0109] The lower plate 33 may include multiple layers for various functions. Adhesive components (not shown) of various polymers may be disposed between the multiple layers included in the lower plate 33. The lower plate 33 may include, for example, a light-shielding layer 33a, a buffer layer 33b, or a lower layer 33c. The light-shielding layer 33a may be interposed between the base film 32 and the buffer layer 33b. The buffer layer 33b may be interposed between the light-shielding layer 33a and the lower layer 33c. The light-shielding layer 33a may block at least a portion of light incident from the outside. For example, the light-shielding layer 33a may include an emboss layer. The emboss layer may be a black layer including an uneven pattern. The buffer layer 33b may mitigate external impacts applied to the flexible display 30. For example, the buffer layer 33b may include a sponge layer or a padding layer. The lower layer 33c may diffuse, disperse, or dissipate heat generated in the electronic device 2 or the flexible display 30. The lower layer 33c may absorb or shield electromagnetic waves. The lower layer 33c may mitigate external impacts applied to the electronic device 2 or the flexible display 30. For example, the lower layer 33c may include a composite sheet 33d or a copper sheet 33e. In embodiments, the composite sheet 33d may be a sheet processed by combining layers or sheets with different properties. For example, the composite sheet 33d may include at least one of polyimide and graphite. The composite sheet 33d may be replaced by a single sheet comprising one material (e.g., polyimide or graphite). The composite sheet 33d may be interposed between the buffer layer 33b and the copper sheet 33e. The copper sheet 33e may be replaced by various other metal sheets. In some embodiments, at least a portion of the lower layer 33c is a conductive member (e.g., a metal plate), which may help enhance the rigidity of the electronic device 2, shield ambient noise, and dissipate heat from peripheral heat dissipation components (e.g., display driving circuitry (e.g., DDI)). The conductive member may include at least one of, for example, copper (Cu), aluminum (Al), stainless steel (SUS), or CLAD (e.g., a stacked member of alternating SUS and Al). The lower layer 33c may include various layers for various other functions. According to various embodiments (not shown), at least one additional polymer layer (e.g., a layer comprising PI, PET, or TPU) other than the base film 32 may be further disposed in the rear surface of the display panel 31. In various embodiments, at least one of the multiple layers included in the underside panel 33 (e.g., light-shielding layer 33a, buffer layer 33b, composite sheet 33d, and copper sheet 33e) may be omitted. In various embodiments, the arrangement order of the multiple layers included in the underside panel 33 is not limited to... Figure 4The embodiments are described, and various modifications can be made. The optical layer 34 may include, for example, a polarizing layer (or polarizer) or a retardation layer (or retarder). The polarizing layer and retardation layer can improve the outdoor visibility of the screen. The optical layer 34 can, for example, selectively transmit light generated from a light source of the display panel 31 and vibrating in a predetermined direction. In some embodiments, a single layer in which the polarizing layer and retardation layer are combined can be provided, and such a layer can be defined as a “circularly polarized layer.” An optically transparent adhesive member 36 can be inserted between the transparent cover 35 and the optical layer 34. In some embodiments, the polarizing layer (or circularly polarized layer) can be omitted, in which case a black pixel definition layer (PDL) and / or a color filter can be provided instead of the polarizing layer. The electronic device 2 may include touch sensing circuitry (e.g., a touch sensor) (not shown). The touch sensing circuitry can be implemented as a transparent conductive layer (or film) based on various conductive materials such as indium tin oxide (ITO). In embodiments, the touch sensing circuitry can be disposed between the transparent cover 35 and the optical layer 34 (e.g., add-on type). In another embodiment, touch sensing circuitry may be disposed between optical layer 34 and display panel 31 (e.g., on-cell type). In another embodiment, display panel 31 may include touch sensing circuitry or touch sensing functionality (e.g., in-cell type). In some embodiments, display panel 31 may be formed based on OLED and include encapsulation 31c disposed between light-emitting layer 31a and optical layer 34. Encapsulation 31c may serve as a pixel protection layer for protecting multiple pixels of light-emitting layer 31a. In an embodiment (not shown), flexible display 30 may include a conductive pattern such as a metal mesh (e.g., aluminum mesh) as touch sensing circuitry disposed in encapsulation 31c between encapsulation 31c and optical layer 34. For example, corresponding to bending of flexible display 30, metal mesh may have greater durability than a transparent conductive layer implemented with ITO. In some embodiments, flexible display 30 may further include a pressure sensor (not shown) capable of measuring touch intensity (pressure). The multiple layers included in display panel 31 or lower panel 33, their stacking structure, or stacking order may vary. The flexible display 30 can be achieved by omitting some components or adding others, depending on its form or convergence trend.

[0110] According to an embodiment, the support sheet 70 may cover at least a portion of the lower panel 33 of the flexible display 30 and be attached to the rear surface of the lower panel 33. The support sheet 70 may be made of various metallic and / or non-metallic materials (e.g., polymers). The support sheet 70 may include, for example, stainless steel. As another example, the support sheet 70 may include engineering plastics. In some embodiments, the support sheet 70 may be integrally implemented with the flexible display 30.

[0111] According to an embodiment, the support sheet 70 may include a mesh structure that at least partially overlaps with a curved portion of the flexible display 30 (e.g., the second region ②, the first curved portion S2 of the screen S). The mesh structure may include, for example, a plurality of openings (or slits) 701. For example, the plurality of openings 701 may be formed periodically, have substantially the same shape, and be arranged repeatedly at regular intervals. The mesh structure may contribute to the flexibility of the second region ②, and the second region ② may be more flexible than the first region ① due to the mesh structure. In some embodiments, the support sheet may include a recessed pattern (not shown) comprising a plurality of recesses, instead of the mesh structure. In various embodiments, the mesh structure or recessed pattern that contributes to the flexibility of the flexible display 30 may extend to at least a portion of the first flat portion S1 of the screen S. In some embodiments, the support sheet 70 including the mesh structure or recessed pattern, or the corresponding conductive member, may be formed in multiple layers. The support sheet 70 may make components (e.g., multi-bar structures) located inside the electronic device 2 substantially invisible through the flexible display 30. The grid structure of the support sheet 70 corresponding to the second region ② of the flexible display 30 includes multiple openings 701, but the multi-bar structure (e.g., the display support structure 50) allows light of a substantially invisible horizontal direction to pass through the flexible display 30. The grid structure of the support sheet 70 corresponding to the second region ② of the flexible display 30 includes multiple openings 70, but the multiple support bars of the multi-bar structure prevent the appearance of protrusion through the flexible display 30.

[0112] In the extended state of screen S (e.g., Figure 6 In the open state, the screen may become uneven due to the lifting caused by the elasticity of the flexible display 30 and / or the support sheet 70. In an embodiment, to prevent such lifting, a tension device (or tension structure) (not shown) for the flexible display 30 and / or the support sheet 70 can be formed. The tension device can facilitate smooth sliding operation while maintaining tension applied to the flexible display 30 and / or the support sheet 70. The tension device can apply tension to the flexible display 30 and the support sheet 70 using, for example, a band (e.g., a wire type or chain band). As another example, the tension device can apply tension to the flexible display 30 and the support sheet 70 using an elastic member such as a spring. When the tension of the tension device is within a threshold range, the second region ② of the flexible display 30 can... Figure 5 The closed state or Figure 6 In the open state, it remains in the form of a smooth connection to the first region ① of the flexible display 30 without being raised. When the tension of the tension device is within the threshold range, the second region ② can... Figure 5 The closed state and Figure 6The movement maintains a smooth connection to the first region ① without any lifting during the switching between open and closed states. When the tension of the tension device is within the threshold range, the sliding operation can... Figure 5 The closed state and Figure 6 The transition between open and closed states is achieved smoothly. For example, when the tension of the tensioning device is below a threshold range, due to the elasticity of the flexible display 30 and / or the support sheet 70, the second region ② may be raised or may not be smoothly positioned within the first region ①. As another example, when the tension of the tensioning device is above the threshold range, the second region ② can be smoothly connected to the first region ① without being raised, but... Figure 5 The closed state and Figure 6 It may be difficult to perform a swipe operation smoothly or gently when switching between open states.

[0113] According to an embodiment, in order to reduce the friction between the bent portion 422a of the fourth support member 422 and the display support structure 50, a lubricant (e.g., grease) may be inserted between the bent portion 422a and the display support structure 50. In some embodiments, in order to reduce the friction between the bent portion 422a of the fourth support member 422 and the display support structure 50, the surface of the bent portion 422a or the surface of the display support structure 50 may be coated with a lubricant.

[0114] According to some embodiments, the fourth support member (e.g., a bending member, a bending support member, or a bending support structure) 422 can be replaced by a rotating member such as a roller or pulley. For example, one end of the rotating member's axis of rotation can be rotatably connected to the third support structure 61, and the other end of the rotating member's axis of rotation can be rotatably connected to the fourth support structure 62. In some embodiments, the rotating member can be defined or interpreted as a bending member, a bending support member, or a bending support structure that is rotatably implemented based on friction with the display support structure 50.

[0115] Although not shown, electronic devices including expandable screens are not limited to those shown in the figure. Figure 4 The electronic device 2 is an embodiment of the present invention, and may be provided in various other forms. In some embodiments, the electronic device may be configured such that the flexible display can be located in a rolled-up state within the internal space of the electronic device (or housing) in a reduced-screen state. In this case, the flexible display may be referred to as a "rollable display". An electronic device including a rollable display may include... Figure 4 The display support structure 50 and the track portion for guiding the movement of the display support structure 50 (e.g., Figure 4 (First guide rail 611, second guide rail 612).

[0116] Figure 7A cross-sectional structure of a display assembly 700 according to an embodiment is shown.

[0117] Reference Figure 7 The display assembly 700 may include, for example, a flexible display 30, a display support structure 50, or a support sheet 70.

[0118] According to an embodiment, the display support structure (e.g., a multi-bar structure) 50 may include a first layer 51 and a second layer 52, the second layer 52 including a plurality of support rods (or a multi-bar structure). The first layer 51 may be interposed between the support sheet 70 and the second layer 52. The first layer 51 may have a flexible film shape or sheet shape. The plurality of support rods may have substantially the same cross-sectional shape and be arranged at a predetermined distance from each other. In some embodiments, some of the plurality of support rods may be arranged at a first separation distance, and other portions of the plurality of support rods may be arranged at a second separation distance different from the first separation distance. Due to the separate arrangement of the plurality of support rods on the first layer 51 and the flexibility of the first layer 51, the display support structure 50 may be flexible. The first layer 51 may include a first region in which the plurality of support rods are disposed and a second region between the first region. The display support structure 50 may bend due to the second region.

[0119] The plurality of support rods included in the second layer 52 may include a first surface 521 facing the first layer 51 and a second surface 522 positioned opposite to the first surface 521. In embodiments, the plurality of support rods may have a cross-sectional shape (e.g., a trapezoidal shape) that narrows in the direction from the first surface 521 to the second surface 522. Such a cross-sectional shape may contribute to allowing the display support structure 50 to bend with a small radius of curvature. The cross-sectional shape of the plurality of support rods is not limited to the illustrated embodiment and may vary. In some embodiments, the second surface 522 may be formed with respect to the support rods included in the second layer 52. Figure 4 The curved shape corresponding to the curved portion 422a in the fourth support member 422. In some embodiments, the second surface 522 may be formed as a curved surface having a raised shape in the direction from the first surface 521 to the second surface 522.

[0120] According to an embodiment, two edge regions 521a and 521b of the first surface 521 included in a plurality of support rods can be formed into curved or inclined shapes separate from the first layer 51. The two edge regions 521a and 521b having curved or inclined surface shapes can contribute to the smooth bending of the first layer 51. The two edge regions 521a and 521b with curved or inclined surface shapes can also contribute to flexibility, allowing the display support structure 50 to bend with a small radius of curvature.

[0121] When in Figure 5 The closed state and Figure 6When switching between open and closed states, the stress acting on the first layer 51 of the display support structure 50 may include tensile stress or bending stress. The tensile stress acting on the first layer 51 may, for example, be proportional to the tensile force acting on the first layer 51 and inversely proportional to the cross-sectional area of ​​the first layer 51. The bending stress acting on the first layer 51 may be proportional to, for example, the elastic modulus (tensile strength or compressive strength) of the first layer 51 and / or the thickness of the first layer 51, and may also be proportional to, the stresses included in, the tensile or compressive strength of the first layer 51. Figure 4 The radius of curvature of the curved portion 422a in the fourth support member 422 is inversely proportional to that of the first layer 51. Figure 5 The closed state and Figure 6 To mitigate the risk of breakage during switching between open and closed states, the shape or material of the first layer 51 can be chosen in consideration of tensile or bending stresses. For example, the first layer 51 may comprise a non-metallic material (e.g., a polymer) or a metallic material. The first layer 51 may be formed with sufficient thickness to ensure the bending characteristics of the display support structure 50.

[0122] According to an embodiment, the first layer 51 and the second layer 52 may comprise the same material. For example, the first layer 51 and the second layer 52 may be integrally formed. As another example, the display support structure 50 may be formed by providing each of the first layer 51 and the second layer 52 and then bonding them together.

[0123] According to some embodiments, the first layer 51 and the second layer 52 may comprise different materials. The second material included in the second layer 52 may have greater strength or greater rigidity (or rigidity properties) than the first material included in the first layer 51.

[0124] According to an embodiment, the first layer 51 and the second layer 52 may include metallic materials. For example, the first layer 51 and the second layer 52 may include the same metallic material. As another example, the first layer 51 may include a first metallic material, and the second layer 52 may include a second metallic material different from the first metallic material. The first metallic material of the first layer 51 may include a material that has an affinity for bonding with the support sheet 70 and the second metallic material of the second layer 52.

[0125] According to some embodiments, the first layer 51 may include a first polymer, and the second layer 52 may include a second polymer different from the first polymer. The first polymer included in the first layer 51 may have greater flexibility (or flexibility properties) than the second polymer included in the second layer 52. The first polymer may be a variety of materials, such as, for example, PET, PI, or TPU. The first polymer may contribute to the bonding strength between the support sheet 70 and the second layer 52, as well as the durability of the display support structure 50. The first polymer may include materials that have bonding affinity with the second polymer of the second layer 52 and the support sheet 70. Depending on the flexibility properties of the first polymer, the first layer 51 may ensure the thickness formation of the bending properties of the display support structure 50. The second polymer included in the second layer 52 may have greater strength or rigidity (or stiffness properties) than the first polymer included in the first layer 51. The second polymer may include, for example, engineering plastics (e.g., polycarbonate (PC) or polymethyl methacrylate (PMMA)). As another example, the second polymer may include materials that are engineering plastics mixed with various reinforcing substrates such as glass fibers or carbon fibers (e.g., fiber-reinforced plastics (FRP)). Due to the rigidity of the second polymer, the second layer 52 can support the second region ② in order to maintain the second region ② of the flexible display 30 (see...). Figure 4 , Figure 5 or Figure 6 ) and the first region ① of the flexible display 30 (see Figure 4 , Figure 5 or Figure 6 The second layer 52, which includes the second polymer, is disposed in the support sheet 70 without the first layer 51. Due to the rigid nature of the second polymer, it may be difficult to ensure the bonding force between the second layer 52 and the support sheet 70.

[0126] According to some embodiments, the first layer 51 may comprise a polymer, and the second layer 52 may comprise a metallic material. In this case, to increase the mechanical bonding force between the first layer 51 and the second layer 52, a bonding structure may also be provided, wherein a portion of the first layer 51 is located in a hole or groove formed in the second layer 52 (e.g., anchoring effect).

[0127] According to some embodiments, the first layer 51 can be omitted, in which case the support sheet 70 can replace the first layer 51.

[0128] According to some embodiments, the display support structure 50 or the first layer 51 can be used as the support sheet 70, in which case the support sheet 70 can be omitted.

[0129] According to some embodiments, when the movement is in Figure 4When the display support structure 50 is transferred between the fourth support member 422 and the display support structure 50, the second layer 52 of the display support structure 50 can have sufficient elasticity to ensure friction with the fourth support member 422, thereby reducing its loss. The second layer 52 can extend between the fourth support member 422 and the second region ② of the flexible display 30 to have elastic contact including Figure 4 The elastic modulus of the bent portion 422a in the fourth support member 422.

[0130] Figure 8 This is an exploded view showing a plurality of support rods 800 included in the display support structure 50 according to an embodiment. Figure 9 An example is shown. Figure 8 Multiple support rods, 800.

[0131] Reference Figure 8 and Figure 9 Each of the plurality of support rods (or multiple support rods) 800 may include a first portion 801, a second portion 802, and a third portion 803 between the first portion 801 and the second portion 802. The third portion 803 may extend straight in a direction from the first portion 801 to the second portion 802 (e.g., the +y axis direction). In some embodiments, the first portion 801 is one end of the support rod and may be referred to as the "first end," and the second portion 802 is the other end of the support rod and may be referred to as the "second end." The second region ② of the flexible display 30 (see...) Figure 4 The third portion 8031 ​​can be positioned corresponding to a third portion of the plurality of support rods 800 located between the first portion 8011 and the second portion 8021. In some embodiments, the third portion 803 is a portion of the support rod that supports the second region ② of the flexible display 30, and may be referred to as a "support portion" or "display support portion". In embodiments, the first type of support rod 810 and the second type of support rod 820 may be arranged repeatedly among the plurality of support rods 800.

[0132] For example, the first portion 801 included in the first type of support rod 810 may include a rotating device 901. The rotating device 901 may include a protruding first shaft 910 extending in a direction from the second portion 802 to the first portion 801 (e.g., the -y-axis direction), a rotating portion (or rotating member) 920 rotatably coupled to the first shaft 910, and / or an anti-separation portion (or anti-separation member) 930 fastened to the first shaft 910. The first shaft 910 may have, for example, a round rod shape having a first diameter D1. The first shaft 910 and the third portion 803 of the first type of support rod 810 may be integrally formed and comprise the same material (e.g., a metallic material). The rotating portion 920 may be, for example, a rotating member or a rolling member, such as an annular roller including a hole 921, and including a circular outer peripheral surface (or cylindrical surface) 922 and a circular inner peripheral surface 923. The rotating portion 920 may be rotatably located on the first shaft 910 through the hole 921. In an embodiment, the first shaft 910 may include a first extension 913 rotatably located therein of the rotating portion 920, and a second extension 914 extending from the first extension 913 and protruding from the rotating portion 920. In some embodiments, the first shaft 910 may be referred to by another term, such as "first pin". To reduce the loss of motion transmission or force transmission by reducing the friction between the first shaft 910 and the rotating portion 920, a lubricant (e.g., grease) may be inserted between the first shaft 910 and the rotating portion 920, or the surface of the first shaft 910 and / or the inner circumferential surface 923 of the rotating portion 920 may be coated with a lubricant. An anti-separation portion 930 may prevent the rotating portion 920 from separating from the first shaft 910. The anti-separation portion 930 may be, for example, an E-ring (e.g., an E-type anti-separation ring). The first shaft 910 (e.g., the second extension 914) may include a recess 911 formed in a cylindrical surface, and the E-ring may be fastened to the first shaft 910 in the recess 911. The rotating part 920 can be inserted between the third part 803 and the E-ring, and the E-ring can prevent the rotating part 920 from separating. The second part 802, included in the first type of support rod 810, can be formed in substantially the same manner as the first part 801. The second part 802 may include a rotating device, which includes a rotating part 950 that is substantially symmetrical to the rotating device 901 of the first part 801 based on the third part 803.

[0133] According to an embodiment, the third portion 803 included in the second type of support rod 820 may be substantially the same as the third portion 803 included in the first type of support rod 810.

[0134] According to an embodiment, the first portion 801 included in the second type support rod 820 may include a protruding second shaft 902 extending in a direction from the second portion 802 to the first portion 801 (e.g., the -y-axis direction). The second shaft 902 may have, for example, a round rod shape having a second diameter D2. The second shaft 902 and the third portion 803 of the second type support rod 820 may be integrally formed and comprise the same material (e.g., a metallic material). The second shaft 902 and the first shaft 910 included in the first type support rod 810 may extend the same length in the y-axis direction. In some embodiments, the first shaft 910 and the second shaft 902 may extend different lengths in the y-axis direction.

The first shaft 1010 may extend from the third portion 803 and has a round rod shape having a diameter. The rotating portion 1020 may be an annular roller including a hole 1021 and including a circular outer peripheral surface 1022 and a circular inner peripheral surface 1023. The rotating portion 1020 may be rotatably located on the first shaft 1010 penetrating the hole 1021. In order to reduce the loss of motion transmission or force transmission by reducing the friction between the first shaft 1010 and the rotating portion 1020, a lubricant (e.g., grease) may be inserted between the first shaft 1010 and the rotating portion 1020, or the surface of the first shaft 1010 and / or the inner peripheral surface 1023 of the rotating portion 1020 may be coated with a lubricant. The anti-separation part 1030 prevents the rotating part 1020 from separating from the first shaft 1010 and includes, for example, a bolt. A thread formed in the shaft 1031 of the bolt can be tightened into a bolt fastening hole 1011 formed in the first shaft 1010. The rotating part 1020 can be inserted between the third part 803 and the bolt head 1032, and the bolt head 1032 prevents the rotating part 1020 from separating.

[0140] Reference Figure 11The rotating device 1101 included in the first portion 801 of the support rod 1100 may include, for example, a rotating portion 1110 and / or a bolt 1120. The rotating portion 1110 may be an annular roller including a hole 1111 and including a circular outer peripheral surface 1112 and a circular inner peripheral surface 1113. The bolt 1120 may include a head 1121 and a round rod-shaped shaft 1122. The shaft 1122 of the bolt 1120 may include a thread 1122a and an unthreaded portion 1122b between the head 1121 and the thread 1122a. The rotating portion 1110 may be rotatably located in the unthreaded portion 1122b included in the shaft 1122 of the bolt 1120 through the hole 1111. The thread 1122a of the shaft 1122 may be fastened to a bolt fastening hole 1130 formed in the third portion 803. The rotating part 1110 can be inserted between the third part 803 and the head 1121 of the bolt 1120, and the head 1121 of the bolt can prevent the rotating part 1120 from separating. In order to reduce the loss of motion transmission or force transmission by reducing the friction between the rotating part 1110 and the unthreaded part 1122b, a lubricant (e.g., grease) can be inserted between the rotating part 1110 and the unthreaded part 1122b, or the inner circumferential surface 1113 of the rotating part 1110 and / or the surface of the unthreaded part 1122b can be coated with a lubricant.

[0141] Reference Figure 12 The rotating device 1201, included in the first portion 801 of the support rod 1200, may include, for example, a first shaft 1210 and a rotating portion 1220. The first shaft 1210 may have a round rod shape extending from the third portion 803. In an embodiment, the first shaft 1210 may include a first region 1211 of a first diameter D1, a second region 1212 of a second diameter D2, and a third region 1213 of a third diameter D3. The second region 1211 may be inserted between the first region 1211 and the third region 1213, and the third region 1213 may be inserted between the third portion 803 and the second region 1212. The second diameter D2 may be smaller than the first diameter D2 and the third diameter D2. The first diameter D1 may be the same as or different from the third diameter D3. In some embodiments, the second diameter D2 and the third diameter D3 may be formed identically.

[0142] The rotating portion 1220 may be, for example, an annular roller including a hole 1221, and includes a circular outer peripheral surface 1222 and a circular inner peripheral surface 1223. The rotating portion 1220 may be rotatably located in a second region 1212 of a first shaft 1210 penetrating the hole 1221. In an embodiment, during assembly for positioning the rotating portion 1220 in the second region 1212 of the first shaft 1210, interference may occur when the rotating portion 1220 is pressed so that the first region 1211 of the first shaft 1210 passes through the hole 1221 of the rotating portion 1220. This interference may occur because, for example, the first diameter D1 of the first region 1211 is larger than the fourth diameter D4 of the inner peripheral surface 1223 of the rotating portion 1220. When an external force corresponding to the interference is applied, the first region 1211 of the first shaft 1210 may pass through the hole 1221 of the rotating portion 1220 due to the elasticity of the first shaft 1210 and / or the rotating portion 1220. With the rotating part 1220 located in the second region 121 of the first shaft 1210, the first region 1211 of the first shaft 1210 can prevent the rotating part 1220 from separating from the first shaft 1210. In order to reduce the loss of motion transmission or force transmission by reducing the friction between the second region 1212 and the rotating part 1220, a lubricant (e.g., grease) can be inserted between the second region 1212 and the rotating part 1220, or the surface of the second region 1212 and / or the inner peripheral surface 1223 of the rotating part 1220 can be coated with a lubricant.

The rolling bearing may include, for example, a circular outer peripheral surface (e.g., Figure 8 922 outer peripheral surface Figure 10 1022 outer peripheral surface Figure 11 outer peripheral surface 1112 or Figure 12 The outer ring of the outer peripheral surface 1222) forms a circular inner peripheral surface (e.g., Figure 8 The inner peripheral surface 923, Figure 10 1023, outer peripheral surface Figure 11 outer peripheral surface 1113 or Figure 12 The outer peripheral surface 1223) of the inner ring, a rolling element such as a ball or roller located between the inner ring and the outer ring, and a retainer that holds the rolling element at regular intervals. In some embodiments, according to Figure 8 The rotating part 920 of the embodiment Figure 10 Rolling component 1020 Figure 11 Rolling member 1110 or Figure 12 The rotating part 1220 can be implemented as a sliding bearing, and some corresponding components can be modified or omitted. Various other types of radial bearings can be used as the rotating part.

The second part 1302 included in the fourth type support rod 1320 can be connected with according to Figure 9 The embodiments include a second portion 802 that is substantially the same as that in the first type of support rod 810. For example, the second portion 1302 included in the fourth type of support rod 1320 may include a rotating device 1322. In embodiments, the rotating device 1311 included in the first portion 1301 of the third type of support rod 1310 and the shaft 1321 included in the first portion 1301 of the adjacent fourth type of support rod 1320 may be positioned separately so as not to interfere with each other. The shaft 1312 included in the second portion 1302 of the third type of support rod 1310 and the rotating device 1322 included in the second portion 1302 of the adjacent fourth type of support rod 1320 may be positioned separately so as not to interfere with each other.

[0150] Reference Figure 14 Each of the plurality of support rods (or multiple support rods) 1400 may include a first portion 1401, a second portion 1402, and a third portion 1403 between the first portion 1401 and the second portion 1402. In an embodiment, among the plurality of support rods 1400, a first type of support rod 1410 may be arranged repeatedly. The first type of support rod 1410 may be coupled with... Figure 8 The first type of support rod 810 in the embodiment is substantially the same. For example, the first type of support rod 1410 may include a rotating device 1411 located in the first portion 1401 (e.g., Figure 8 The rotating device 901 is located in the first part 1401 of the first type support rod 1410, and the rotating device 1412 is located in the second part 1402. In the embodiment, the rotating device 1411 included in the first part 1401 of the first type support rod 1410 and the rotating device 1411 included in the first part 1401 of another first type support rod 1410 adjacent to it can be positioned separately so as not to interfere with each other. The rotating device 1412 included in the second part 1402 of the first type support rod 1410 and the rotating device included in the second part 1402 of another first type support rod 1410 adjacent to it can be positioned separately so as not to interfere with each other.

[0151] Figure 15 The flexible display 30 and a plurality of support rods 800 are shown according to an embodiment (see Figure 8 or Figure 9 The display support structures 50 are connected to each other. Figure 16 An example is shown. Figure 4 The third supporting structure 61.

[0152] Reference Figure 4 , Figure 8 , Figure 9 , Figure 15 and Figure 16 The first portion 801 of the plurality of support rods 800 may be located at or inserted into the first guide rail 611 included in the third support structure 61. The first guide rail 611 may include a groove or recess corresponding to the movement path of the display support structure 50. When the state of the electronic device 2 changes (e.g., in...), Figure 5 The closed state and Figure 6 During the switching between open and closed states, the first portion 801 of the plurality of support rods 800 can be guided and moved to the first guide rail 611. The second portion 802 of the plurality of support rods 800 can be located at or inserted into the second guide rail 621 of the fourth support structure 62. During the state change of the electronic device 2, the second portion 802 of the plurality of support rods 800 can be guided and moved to the second guide rail 621. During the state change of the electronic device 2, when the first portion 801 of the plurality of support rods 800 is guided and moved to the first guide rail 611, the rotating portion 920 located in the first portion 801 can rotate by friction with the first guide rail 611, thereby reducing the friction between the display support structure 50 and the first guide rail 611. During a change of state in electronic device 2, when the second portion 802 of the plurality of support rods 800 is guided and moved to the second guide rail 621, the rotating portion 950 located in the second portion 802 can rotate due to friction with the second guide rail 621, thereby reducing the frictional force between the display support structure 50 and the second guide rail 621. During a change of state in electronic device 2, when the frictional force between the display support structure 50 and the first guide rail 611 and the frictional force between the display support structure 50 and the second guide rail 621 decreases, a smooth and gentle sliding motion can be achieved by reducing the loss of motion transmission or force transmission. For example, during a change of state in electronic device 2, the rotating portion 920 located in the first portion 801 and the rotating portion 950 located in the second portion 802 can reduce the influence of friction between the display support structure 50 and the guide rail on the sliding operation when the display support structure 50 moves while changing direction corresponding to the bending portion 422a. Even when the display support structure 50 is implemented to include according to Figure 13 Multiple support rods 1300 in the embodiments or according to Figure 14 When multiple support rods 1400 are used in the embodiment, a smooth and gentle sliding operation can also be achieved due to the same principle.

[0163] According to some embodiments, the third surface 1803 may be formed as an inclined surface that is not parallel to the first surface 1801. In some embodiments, the fourth surface 1804 may be formed as an inclined surface that is not parallel to the second surface 1802.

[0164] According to some embodiments, the fifth surface 1805 may be formed as an inclined surface that is not perpendicular to the first surface 1801 or the third surface 1803. In some embodiments, the fourth surface 1804 may be formed as an inclined surface that is not perpendicular to the second surface 1802 or the fourth surface 1804.

[0165] According to an embodiment, electronic device 2 may include a centerline C (see...) Figure 2a , Figure 2b , Figure 3a or Figure 3b )about Figure 4 The second guide rail 621 and Figure 20 The cross-sectional structure shown in 2000 is a substantially symmetrical cross-sectional structure (e.g., Figure 4 The cross-sectional structure of the fourth support structure 62, the third cover portion 222c, and the third support member 421.

[0166] Figure 21 The schematic illustration shows the connection to the flexible display 30 according to an embodiment. Figure 8 The cross-sectional structure 2100 of some of the multiple support rods 800 2110 is located in the first track portion 611a of the first guide rail 611.

[0167] Reference Figure 19 , Figure 20 and Figure 21 The first shaft 910, rotating part 920, and anti-separation part 930 located in some support rods 2110 can be inserted into the first track part 611a of the first guide rail 611. The first shaft 910 can be partially inserted into the second recess 2032 through the first recess 2031. The first shaft 910 may include a portion protruding in the +y axis direction relative to the anti-separation part 930 (e.g., Figure 8 and Figure 21 The second extension portion 914), and the second recess 2032 can be used to receive this portion. The rotating portion 920 and the anti-separation portion 930 can be located in the first recess 2031. The outer peripheral surface 922 of the rotating portion 920 (see...) Figure 8 The third diameter D3 of the first shaft 910 can be smaller than the first width W1 of the first recess 2031. The first diameter D1 of the first shaft 910 can be smaller than the second width W2 of the second recess 2032. In the state change of the electronic device 2 (e.g., switching between a closed state and an open state), when the first portion 801 of the plurality of support rods 800 (see...) Figure 8 When guided and moved to the first guide rail 611, the rotating part 920 can rotate by friction with the first surface 1801 or the second surface 1802 of the first track part 611a.

[0168] According to an embodiment, the difference between the third diameter D3 and the first width W1 can be less than the difference between the first diameter D1 and the second width W2. Therefore, the rotating part 920 can contact the first surface 1801 or the second surface 1802 of the first track part 611a, but the first shaft 910 may not contact the third surface 1803 and the fourth surface 1804 of the first track part 611a. When the state of the electronic device 2 changes (e.g., in…), Figure 5 The closed state and Figure 6 In the switching between open and closed states, since the first shaft 910 does not contact the third surface 1803 and the fourth surface 1804 of the first track section 611a, the motion transmission loss or force transmission loss caused by friction can be reduced.

[0169] According to an embodiment, when viewed in the y-axis direction, the anti-separation portion 930 may overlap with the fifth surface 1805 and / or the sixth surface 1806. Due to interference between the anti-separation portion 930 and the fifth surface 1805 (or the sixth surface 1806), Figure 7 The movement of the display assembly 700 in the +y axis direction can be restricted. Therefore, the end 912 of the first axis 910 may not contact the surface of the second recess 2032 in the first track portion 611a. During changes in the state of the electronic device 2, because the end 912 of the first axis 910 does not contact the surface of the first track portion 611a, motion transmission loss or force transmission loss due to friction can be reduced. In some embodiments, in the first track portion 611a, the third surface 1803 and the fifth surface 1805 may be omitted, and the first surface 1801 may be extended. In some embodiments, in the first track portion 611a, the fourth surface 1804 and the sixth surface 1806 may be omitted, and the second surface 1802 may be extended.

[0170] According to some embodiments, when Figure 7 When the display assembly 700 moves in the +y direction, the end 912 of the first shaft 910 can contact the surface of the second recess 2032 facing it, but the anti-separation portion 930 can avoid contacting the fifth surface 1805 and / or the sixth surface 1806. During changes in the state of the electronic device 2, because the anti-separation portion 930 does not contact the fifth surface 1805 and / or the sixth surface 1806, motion transmission loss or force transmission loss due to friction can be reduced.

The second shaft 902 can be partially inserted into the second recess 2032 through the first recess 2031. The second diameter D2 of the second shaft 902 can be smaller than the second width W2 of the second recess 2032. In an embodiment, the first diameter D1 of the rotating portion 920 (see...) Figure 21 The difference between the first diameter D2 of the second shaft 902 and the first width W1 of the first recess 2031 can be less than the difference between the second diameter D2 of the second shaft 902 and the second width W2 of the second recess 2032. Therefore, the first portion 801 of a first type of support rod 810 (see...) Figure 8 or Figure 9 The rotating part 920 in the first track part 611a can contact the first surface 1801 or the second surface 1802, but because Figure 7 Due to the elasticity of the display assembly 711, the second shaft 902 located in the first portion 801 of the adjacent second-type support rod 820 may have difficulty contacting the third surface 1803 and the fourth surface 1804 of the first track portion 611a. During changes in the state of the electronic device 2, because the second shaft 902 does not contact the surfaces of the first track portion 611a, motion transmission losses or force transmission losses due to friction can be reduced.

The first shaft 910 can be partially inserted into the second recess 2032 through the first recess 2031. The rotating part 920 and the anti-separation part 930 can be located in the first recess 2031. The outer peripheral surface 922 of the rotating part 920 (see...)

The first diameter D1 of the first shaft 910 can be smaller than the second width W2 of the second recess 2032. In the state change of the electronic device 2 (e.g., switching between a closed state and an open state), when the first portion 801 of the plurality of support rods 800 (see...) Figure 8 When guided and moved to the first guide rail 611, the rotating part 920 can rotate by friction with the first surface 1801 or the second surface 1802 of the second track part 611b.

[0176] According to an embodiment, the difference between the third diameter D3 and the first width W1 can be less than the difference between the first diameter D1 and the second width W2. Therefore, the rotating part 920 can contact the first surface 1801 or the second surface 1802 of the second track part 611b, but the first shaft 910 may not contact the third surface 1803 and the fourth surface 1804 of the second track part 611b. During changes in the state of the electronic device 2, because the first shaft 910 does not contact the surfaces of the second track part 611b (e.g., the third surface 1803 and the fourth surface 1804), motion transmission loss or force transmission loss due to friction can be reduced.

[0177] According to an embodiment, when viewed in the y-axis direction, the anti-separation portion 930 may overlap with the fifth surface 1805 and / or the sixth surface 1806. Due to interference between the anti-separation portion 930 and the fifth surface 1805 (or the sixth surface 1806), Figure 7 The movement of the display assembly 700 in the +y axis direction can be restricted. Therefore, the end 912 of the first axis 910 may not contact the surface of the second recess 2032 in the second track portion 611b. During changes in the state of the electronic device 2, because the end 912 of the first axis 910 does not contact the surface of the second track 611b, motion transmission loss or force transmission loss due to friction can be reduced. In some embodiments, in the second track portion 611b, the third surface 1803 and the fifth surface 1805 may be omitted, and the first surface 1801 may be extended. In some embodiments, in the second track portion 611b, the fourth surface 1804 and the sixth surface 1806 may be omitted, and the second surface 1802 may be extended.
